STU MIP-PU LLER OR LOAD-LIFTER.

SFECIFICATION forming part of Letters Patent No. 521,251, dated June 12,1894 Application filed September 14, 1893 Serial No. 485.580. (Nomodel.)

To 00% whom it may ooncerm Be it known that I, MILTON ALLMON, a citizenof the United States, residing at Benton, in the county of Franklin andState of Illinois, have invented a new and useful Stump- Puller orLoad-Lifter, of which the following is a specification.

My invention relates to an improved stump puller and load lifter, and ithas for its object to provide a simple, inexpensive and ef ficientdevice for pulling a stump and lifting the same or otherload to thelevel of the body of the vehicle,whereby it maybe moved horizontallyintothe latter.

Further objects and advantages'of this invention will appear in thefollowing description,.and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings: Figure 1 is a perspective view of a device embodying myinvention. Fig. 2v is a similar view looking at the opposite side of themachine.

' Similar numerals of reference indicate corresponding parts in bothfigures of the drawings.

The framework of the device comprises two parts or members 1 and 2, eachof which is constructed of a horizontal rectangular frame 3, mountedupon the supporting standards 4, and the said frames, which are arrangedin alignment and are spaced 'apart so as to 00- cupy positions uponopposite sides of the stump or other load to be lifted, are connected bythe derrick 5, consisting of the inverted V-shaped uprights 6, connectedat their upper ends by the cross-bar 7.

8 represents the drum shaft,which is mounted in bearings in the oppositesides of the framework and carries a drum 9, and a ratchet-wheel 10.

11 represents a bracket mounted upon the same member of the framework asthe said drum shaft and having parallel sides 12 be tween which isfulcrumed the operating lever 13. This lever carries the twin pawls 14:,which are arranged upon opposite sides of the fulcrum of the lever andengage the said ratchet-wheel, whereby as the lever is oscillated thepawls alternately engage and communicate motion to the ratchet-wheel,and through the latter to the shaft. Fixed to the drum shaft isabrake-wheel15, and fulcrumed to the side of the framework, in operativerelation thereto, is a brake-lever 16, which is disposed to operateparallel with and adjacent to one of the sides of the bracket whichsupports the operating lever, said side being provided with a series ofperforations or sockets 17 for the reception of a locking-pin 18, tohold the brake-lever in the desired position. Fixed to the drum shaft,preferably between the sides of the frame, is a clutch-wheel 19, andfulcrumed to the frame, in operative relation to said clutch-wheel, andcontiguous to the opposite side of the bracket from the brake-lever justdescribed, is a locking-lever 20, so disposed as to automatically engagethe clutch-wheel, being held in operative position by gravity. The sideof the bracket adjacent to said locking-lever, is provided with a seriesof perforations 21, for the reception of a locking-pin 22 to hold thelocking-lever out of engagement with the clutch-wheel.

Arranged longitudinally upon the members comprising the framework, is atrack consisting of the parallel rails 23. The portions of these trackrails which span the frames 1 and 2 are fixed in position, and therespective track rails of the two members are connected to span theinterval between the frames by the removable rail-sections 24, which,inFig. 1, are shown displaced to enable the load to be elevated betweenthe frames. After the load has been elevated to a plane above the track,these removable sections are replaced and the load lowered thereupon,after which the latter may be moved longitudinally into the vehicle.

The parallel side plates comprising the bracket'in which the operatinglever is arranged serve as guides for such lever to pre- Vent lateralvibration and disarrangement of the actuating pawls. As above shown,these side plates perform the additional function of supporting the pinswhereby the brake and locking levers are held in the desired positions.

It will be understood that the brake mechanism, comprising thebrake-wheel and lever,

is adapted especially for use in lowering the load upon the track, andthe locking device, comprising the clutch-wheel and locking-lever, isdesigned to secure the load at any do sired elevation and prevent theaccidental dropping of the load after it has been raised.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having described my invention, what I claim is- 1. In a device of theclass described, the combination of a framework comprising independentspaced self-supporting sectionsor members, adapted to be arranged uponopposite sides of the object to be elevated, a derrick connecting saidsections or members and spanning the interval therebetween, a trackarranged longitudinally upon the framework and having removablerail-sections which span the interval between the sections,and elevatingdevices carried by one of the sections, whereby the tracks upon theother section are unobstructed, substantially as specified.

2. In a device of the class described, the

combination of a framework comprising independent spaced sections ormembers connected by a derrick, a track arranged upon said framework andhaving removable railsections to span the interval between the same, adrum shaft provided with a ratchet-wheel, a bracket carried by one ofthe sections and having parallel side plates, an operating leverfulcrumed between the side plates of the bracket and carrying pawls toengage said ratchet -wheel, a brake mechanism having its lever arrangedcontiguous to one of the side plates of the bracket, a clutch devicehaving a gravity lever arranged contiguous to the other side plate ofthe bracket, and locking-pins engaging perforations in said side platesto secure said levers in adjusted position, substantially as specified.
